焊接是连接金属最常用的方法,是工业生产部门(如:机器制造,建筑安装,造船工业,运输工业,石油化工等),广泛采用的重要工艺过程,在多数国家里约有0.5—2％的劳动力从事焊接作业。早在30～40年代就已经有电焊工铁尘肺的报道,近二十年来,对长期接触低浓度焊接粉尘和气体可导致的呼吸系统疾病日益受到重视,流行病学方法也广泛应用在职业卫生危害的评价,本文拟对近年来有关电焊粉尘及其呼吸系统危害的部分资料综述如下。
Welding is the most commonly used method of joining metals and is an important process widely used in industrial production (eg machine building, construction and installation, shipbuilding, transportation, petrochemicals, etc.). In most countries about 0.5-2% The workforce is engaged in welding work. As early as in the 30s and 40s, there have been reports of electrician dust pneumoconiosis. In the past 20 years, respiratory diseases such as long-term exposure to low concentrations of welding dust and gases have received increasing attention. Epidemiological methods are also widely used in occupational health Hazard evaluation, this paper intends to welding dust in recent years and some of its respiratory system hazards are summarized below.
